раз уж топик подняли, продолжу здесь.
1. тест кабелей (межблочных и акустических) от 2 баксов до 900:
In the first test, five specialty interconnects from AudioQuest, MIT, Monster Cable, H.E.A.R., plus Belden cable with Vampire connectors were compared to a $2.50 blister pack RCA phono interconnect. Listeners used Etymotic Research ER4 in-ear phones driven by the headphone jack of a Bryston 2B power amplifier.
The next three tests are the data from Tom Nousaine's "Wired Wisdom: The Great Chicago Cable Caper", listed on the ABX periodicals page.
The Type "T1" cables were compared on a system including an Sumo Andromeda power amp and JS Engineering Infinite Slope speakers, by the system's owner. He chose his own program material and had no time limit.
The Type "Z" cables were tested on the system of a high end audio shop employee including: Snell type B-Minor speakers; Forte Model 6 Power Amp; and an outboard DAC. He used his own program material selected to show the differneces he expected.
The Type "T2" cables were compared on a system including a Denon DCD-1290 CD player, and Accuphase P-300 power amplifier, and Snell KII speakers.
Никто не отличил дешевые провода от дорогих, включая владельцев аудиотехники.
2. Тест "направленных" проводов Belden
The cable maker Belden conducted a test with an un named magazine which found the result was perfectly random.
3. Hi-Fi Wigwam. Что называется, достали и померялись.
four mains cables including 2 kettle leads (stock power cords that had come with hifi products), an audiophile one, a DIY one and a tester CD were sent out forum members. The results were inconclusive to say the least, for example;
The kettle lead was C. There were 23 answers :
4 said that the kettle lead was A
6 said that it was B
8 said that it was C
5 said that they didn't know.
Результаты опять случайные, увы.
4. Очередной тест кабелей (никак не угомонятся)
The kit started out with the cheapest cables WHF could find and no one liked it saying it sounded flat and dull. Then a Lindy mains conditioner and Copperline Alpha power cords were introduced and the sound improved.
The IC was changed to some Atlas Equators and two out the three tracks were said to have improved with better bass and detail.
Last the 60p per metre speaker cable was changed for £6 per metre Chord Carnival Sliverscreen. Again, changes were noticed, but they were not big.
Увы :(
5. Ну и силовые провода протестировали, куда же без этого:
Secrets of Home Theatre and High Fidelity. Can We Hear Differences Between A/C Power Cords? An ABX Blind Test. December, 2004
Результат - никто не опознал дорогой кабель
6. Вот тут ваще жесть - предполагали, что на качество звучания материала влияют любые электрические устройства в комнате - часы, телефоны, наушники и тд. Заодно в тракт включали соневский цифровой процессор. Тест устроил некто Ivor Tiefenbrun, основатель LINN (это которая перестала выпускать CD, перейдя на FLAC). Ни наличие электронных часов возле его головы, ни включение в тракт цифрового процессора он определить, увы, не смог.

11. Журнал Sound & Vision. Проверяли кабели на своих стереосистемах. фэйл :(

Ожидаемый результат - как только доходит до слепого прослушивания, или до тестов ABX, всё становится на свои места.
